Answer of CCNA Discovery : Version 4.1 by -NoNaMeZzz-

Note: These answers will give you 95.6%. Number 14 is incorrect. Please correct if possible.

1
Which two benefits can be gained by locating network equipment in a telecommunications closet, rather than in a user area? (Choose two.)

faster communication speeds

improved physical security

more resistant to hacker attempts

centralized cable management

less electrical usage

2
Which three issues should be noted on the technician’s site survey report? (Choose three.)

unlabeled cables

only two power outlets per wall in each room

poor physical security of network devices

horizontal cabling runs under 100 meters

lack of UPS for critical devices

two users sharing the same computer

3
Which two types of cable are used for initial router configuration? (Choose two.)

serial cable

rollover cable

straight-through cable

crossover cable

patch cable

console cable

4

In addition to the inventory sheet, what other information about the hosts and networking equipment should be documented by the on-site technician while performing the site survey?

any obsolete office equipment being stored

all product keys for site license software

any planned growth anticipated in the near future

the memory requirements for installed application software

Refer to the exhibit. What type of device is used to connect two networks?

hub

router

switch

access point

6
It is said that the goal for availability of a communications system is “five-9s”. What is meant by this?

A down time of .00001% is unacceptable.

A network needs to be available 99.999% of the time.

Five percent of all network expense covers 99% of user requirements.

The most critical time for network availability is from 9:00 to 5:00 p.m. five days a week.

The best time to do maintenance on a network is from 5:00 p.m. to 9:00 a.m. five days a week.

7
What three things are included in a logical topology document? (Choose three.)

the location of cables, computers, and other peripherals

the path that the data takes through a network

the wireless signal coverage area

the wiring closet and access point locations

the device names and Layer 3 addressing information

the location of routing, network address translation, and firewall filtering

8
Which device has the ability to break up broadcast and collision domains?

repeater

hub

router

switch

9
Why is it important to review the results of an on-site survey report with the customer before beginning the network design?

to inform the customer of how much time the upgrade will take

to discuss the implementation schedule for the new equipment

to verify that the report accurately describes the current network and any plans for expansion

to layout the new network design and discuss possible equipment upgrades and replacements

10
A client requires a networking device that is capable of expansion to suit growing network demands. What type of device will suit this requirement?

a networking device with ports that can be activated and deactivated

a networking device with a modular physical configuration

a networking device with the ability to be turned off remotely

a networking device with a cost per port that is as high as possible

11
What does the use of redundant network components supply to a network?

scalability

manageability

compatibility

reliability

12
What is the benefit for a company to use an ISR router?

An ISR provides the functionality of a switch, router, and firewall in one device.

ISRs use a PC operating system for routing traffic, thus simplifying configuration and management.

An ISR is immune to security attacks by hackers and so replaces all other network security measures.

ISRs make routing decisions at OSI Layer 7, thus providing more intelligence to the network than do other routers.

13
Which three items are typically found in an MDF? (Choose three.)

user workstations

switches and routers

fax machines

network equipment racks

the point of presence

copier

14
What are two advantages of having ISP-managed services? (Choose two.)

does not require leasing costs for service

can guarantee up to 99.999% availability

eliminates the need for data backup

increases availability of help desk services

does not require a Service Level Agreement

15
A manufacturing company is in the process of a network upgrade. Which two statements are true about the phases of the upgrade process? (Choose two.)

Phase 1 is used to determine network requirements.

Phase 2 includes creating an analysis report.

Phase 3 is based on an implementation schedule that allows extra time for unexpected events.

Phase 4 is where prototypes are created and tested.

Phase 5 includes identifying and addressing any weaknesses in the design.

16
When designing a network upgrade, which two tasks should the onsite technician perform? (Choose two.)

configure the servers and routers prior to delivery

upgrade the network operating system and all client operating systems

investigate and document the physical layout of the premises

document the final design for approval by the customer

perform a site survey to document the existing network structure

17
What is the term for the location at the customer premise where the customer network physically connects to the Internet through a telecommunications service provider?

backbone area

point of presence

network distribution facility

intermediate distribution frame

Refer to the exhibit. Which type of twisted pair cable is used between each device?

A=console, B=straight, C=crossover, D= crossover, E=straight

A=straight, B=straight, C=straight, D=crossover, E=console

A=crossover, B=straight, C=straight, D=crossover, E=crossover

A=console, B=straight, C=straight, D=crossover, E=crossover

A=console, B=crossover, C=crossover, D=straight, E=straight

19
In what two ways will entering into a managed service agreement with an ISP for a network upgrade affect the costs that are incurred by the customer? (Choose two.)

Customer IT training costs will increase to enable operation of the new equipment.

The cost of hardware repairs and support will become the responsibility of the customer.

Network upgrade and maintenance costs will become predictable.

Staffing costs will increase because the customer will need to hire additional IT staff to complete the upgrade.

The company will not need to spend a large amount of money to purchase the equipment upfront.

20
Which type of cable has a solid copper core with several protective layers including PVC, braided wire shielding, and a plastic covering?

STP

UTP

coaxial

fiber optic

21
What must be added when a network expands beyond the coverage area of the current telecommunications room?

MDF

POP

IDF

IXP
